It is about 26.2 miles.
1 foot = about 0.000189394
They are equivalent. They’re equivalent because 3+6=9 and 3(2+1) also equals 9 2+1 is 3 so you would have 3(3) and whatever number is in the parentheses you just multiply it with the other number and 3*3 is 9
Step-by-step explanation:
A triangle's angles add up to be 180 degrees, so you can create an equation to be 180= 130+5x. (the 5x is 2x + 3x)
subtract 130 from both sides and get 50=5x, divide both sides by 5, x is equal to 10.
I'm not sure which angle is angle a, but if you substitute x with 10, you can find the measure of the angle, so if it's 2x, 2(10)=20 and if 3x, 3(10)=30
